* Original work by Brent Fulgham <bfulgham@debian.org>
* (Based on lots of help from Matthew Flatt)
*
+ * TODO Convert byte-strings to char strings?
+ *
* This consists of six parts:
* 1. MzScheme interpreter main program
* 2. Routines that handle the external interface between MzScheme and
* garbage collector will do it self
* 2. Requires at least NORMAL features. I can't imagine why one may want
* to build with SMALL or TINY features but with MzScheme interface.
- * 3. I don't use K&R-style functions. Anyway, MzScheme headers are ANSI.
